Thanks for the info. I expected that from Longshot because of other data, but am surprised by the 800x. Is your longslide a6 or 6.6 barrel?

6in. I showed no signs of pressure in the mechtech that the longslide did. The chamber is cut in the mechtech to lower chamber pressure by 25% they say. I will have to work up a load in the mechtech and see how far it can be pushed before signs appear. A compressed load of 800x might show some really impressive numbers. 2400 I think has potentional but case capacity I can see being an issue. I have some friends with a few other powders I could try also. H110 the one guy loves in his big bores. Anyone use that powder?

I have used H110 but it was far too slow, it needs to be duplex loaded to light off due to the small case capacity. I got the same or better results from Longshot, though I was using a 5.3" bbl. Maybe better in the long barrel? Yondering had tried 2400 and said it was not worth pursuing, but I don't know the specifics; it is fluffy like H110. I would guess that BlueDot would do pretty well.

If u looked at the longshot load I tested it only picked up 100 fps from longslide to ccu. I don't think longshot likes long barrels. Longshot for me has been a powder that will get u to a good point then goes cold.

The loads I shot the deer with this past fall. The down loaded ones. Forget the data at the moment. 190gr cast.
Long 1410. Ccu 1675.

Sounds to me like you might have been a LITTTTTLE BIT too close to your chrony for the 800X round... (maybe?) because there is no real reason 800X should a) show that much DIFFERENCE than other similar powders and b) show that much change, PERIOD.

Just my .02. Let us know! Cool info here, anyways!

20 ft too close? I was sure to be back a ways. Might have even been 25. It's a good distance away.

I shot 7 rounds of that one cause I was shocked to see that speed. All were right there. The rest I shot 5 of.

Maybe next time out I will shoot again with the go pro recording so u can see it.

No, I believe you...

Wow, those are pretty astounding numbers .... but i just realized that the first increase is 180gr and the last two are 200gr. That's why... (duh, I was in a hurry when I first read it). The 180's will gain a bit more from that faster powder, too.... 200gr bullets will only go so fast with ANY powder ... unless you get a slower powder and cram a bunch in... but even then.... (AA9?) The problem is, regardless of the powder, you will run out of space before you gain in a 200gr what you've gained with 180's....
